Looking to replace my the windscreen washer-jet nozzle (part GNC8977AB) that mounts to the windshield wiper arm - mine never sprayed right due to the rubber being damaged, but I've never seen how the spray is supposed to look when they do work correctly - does washer-fluid spray out each of the 4 tiny rubber nozzles? Does it come out from each as a stream or wide-spray?

[I know this is a goofy question, lol, bear with me plz]

Also, if anyone can part with a properly-working one for $20/shipped to NY, plz PM me

 

they're supposed to spray out of each nozzle, as well as the two metal nozzles towards the center of the washer. I replaced mine with a junkyard one, on the old one one of the rubber nozzles was torn. On the current one it generally only sprays out of the metal ones and sometimes out of one of the rubber ones. I can kind of encourage them to work by unsticking them with something pointy, but they seem to get stuck again if left overnight or whatever. Replacements seem a bit pricey...

It seems to be more of a jet than a wide spray, but it's hard to tell when the wiper's moving. Someone here mentioned an x300 washer retrofit (the nozzles go into the cowl in place of those oval bolt covers) which I've been considering as well, but that will still be streams instead of a wide spray. At least the metal nozzles there will be less likely to stick.

 

The OE system works very well -- should come out of all of them

 

+1 if it works well.
It looks / feels a bit different compared to the traditional system, but if all washers spray, it is as effective, without the water spray going all over the car.

 

Thank you - just ordered a replacement from ebay for $25

Any instructions for replacement? It looks like it has a door that just snaps open and the tube is held on via a barb, so just pull off?

 

Does that seller have any more? If so, link?

It's held on the wiper arm by that clip which latches onto the side of the jet, and the tube is just a barb. First time I did mine I cracked the plastic square piece further down the arm which holds the tube to the wiper arm.

 

I never liked the washer jet being on the wiper arm, it used to freeze up during winter and I wouldn't be able to wash the windscreen. Even using screenwash that's not supposed to freeze didn't work. On a motorway journey this was a problem, particularly at night and on one trip I had to keep stopping to pour bottled water on the screen.

I solved this problem by retrofitting a pair of heated washer jets from an X300 into the scuttle, which itself is an X300 item with blanking plugs where the washers go. I wired the jets into the heated windscreen circuit and have copied this for my current XJ.

 

And that is something a bloke living on a tropical island never thought about
Sounds like a very well thought solution.

 

It's a problem I run into on every day under 35 degrees. The heated retrofit sounds intriguing though. I might have to look into that side.

 

I think he's just parting out a single car, so I doubt it.

How did you crack the square? How can I avoid doing that to mine??

 

Just be gentle when pulling the hose off - when I pulled mine off the jet barb, the hand holding the hose went way far and pulled the house away from the rest of the wiper arm. If it does break that piece should be easy to substitute

the piece I broke is part 5 here http://www.jaguarclassicparts.com/uk...-arm-and-blade

 

LOL. Ok, after reading this post, I looked at mine.
Well, I have 3 of the 4 "jets" working properly.
The 4th one (Top one) shoots a jet at anyone or anything standing on the right side of the car!!!!!!!! Too funny.

So, Now I'm looking for a replacement for this. Thanks for helping me find yet another thing I need to replace :-)

Also, I have found that the wiper arms with multiple "fulcrums" work MUCH better than the arms with none. The fulcrums help the blade conform to the slope and curve of the windshield better.

 

I use the frameless wiper blades, much better than anything with a frame IMO, regardless of fulcrum points. The main issue is longevity - they only work well for a year at best, I've tried every brand and some become hopelessly streak'y after just 6-months (and yes, I do clean the blades regularly...)

 

Same here.
I additionally spent a bit of time to bend the steel strips inside the wiper blade a bit more at the end (but not too much), and my wiper has 100% contact at every position, even in rest.
I simply replace the rubber wiper blade (available loose here), so it was one time operation to have everything lining up.
Yeah, call me a freak .

 

I like this idea, did you wire them into the rear heater, or does your car happen to have a front defroster as well? Also, are the nozzles fine with being heated when not in use (like if only running the rear heater without using the washer) or are they only supposed to be heated "on-demand" when spraying?

 

They are wired into the heated front windscreen circuit, that operates on a timer so that should be enough to de-ice them. There's no reason why you couldn't use the rear screen circuit if you don't have heated front screen. I don't know about leaving them permanently hot, but the mirrors on certain vehicles are permanently heated so I don't see why it could be an issue.

The X300 had some features which were better than the X308 in some areas, this is one of them. A heated washer bottle was also available on the X300 so maybe that may suit you better?

Rpach: the nozzles are adjustable so you might want to try doing that before buying a new one. Just apply gentle pressure to the nibs.

 

Assuming the wiring is still there, I'll probably go back to the X300 set up... The openings in the scuttle bard are still there and you get heated jets whuch can be set up properly... I hate the X308 system. So cheap and nasty! It rarely gets enough water in the areas you need...

 

I'll tell you what I'll do, I'll make a write up or How To guide for you all. I'm off this weekend so I'll go back over my work and take photos and do a write up for you. It's not a difficult task to do.

 

Could you post a part number or a link, please?

The original costs an arm and a leg.

 

Sorry I ever got a chance to make the How To, I was ill at the weekend.
However I've just spotted this on eBay, it looks like a useful alternative.
